A solenoid valve is an electromechanical valve for use with liquid or gas.
The valve is controlled by an electric current through a solenoid coil.

A quick-opening valve which is mounted on a pressurized tank. The opening of
the valve generates a cleaning pulse which dislodges the dust from the filter
elements.

Valve that is actuated with a electromagnetic solenoid magnet. 2 possible
variations, NC (naturally closed) which is closed when there is no current
applied and NO (naturally open) which is open when no current is
applied

A contact of mine (AprilnotMay) recently made a
homemade diffuser and I wanted to have a go at it. This is my milk jug diffuser.
I got the idea of this design from the Lumiquest diffuser. It doesn't look as
pretty as the Lumiquest but it does work. : )
